Obviously, technical manuals are only for experts with a strong technical background to check something or rather to work with. After all, who wants a machine that mistakenly cools instead of heating just because a layman was of the opinion they could “do it well enough”?
Not placing your faith in competent professionals to translate technical manuals can quickly lose you a lot more money than you would have invested up front if you had. For if the translation is not done professionally, people from another language area may well need a great deal of time to get the technical equipment in question up and running – time which can easily turn into financial losses and/or dissatisfaction for the customer.
